Combustion Design Senior Engineer

ABOUT THE ROLE
Job Overview:
The Gas Turbine Combustor Engineer is responsible for the design, analysis, development, and support of combustor systems for micro jet engines. This role involves gathering and interpreting customer requirements and contextualizing the performance criteria in conjunction with the engine performance analysis team. The combustor designer will utilize appropriate tools for each stage of the design process, implementing 1-D and correlation-based modeling during initial sizing phases and leveraging high-fidelity CFD analysis to model complex combustion processes. The designer's focus is on achieving stable combustion, high efficiency, low emissions, reliable ignition, and long life within the constraints of very small engine architectures, where combustor residence time, temperature patterns, and manufacturability present unique challenges. Effective communication across various functions, such as system engineering, mechanical design, materials engineering, and advanced additive manufacturing, is essential. Ultimately, the combustor designer aims to assess requirements, apply innovative tools, maintain a product-centric outlook, and deliver a fit-for-purpose design.

RESPONSIBILITIES

• Define combustor requirements from engine cycle conditions, including thrust class, allowable pressure loss, operability range, emissions intent, and turbine inlet temperature constraints.
• Translate system requirements into a combustor concept by selecting the overall architecture, primary zone arrangement, fuel injection approach, dilution strategy, and cooling philosophy.
• Carry out preliminary sizing and concept development using first-principles methods, empirical correlations, and iterative trade studies to establish feasible geometry and performance.
• Analyse flow field, mixing, ignition, flame stability, liner heat load, and exit temperature distribution to refine the design through successive development stages.
• Evaluate design sensitivities to geometry, fuel scheduling, airflow split, and manufacturing tolerance to improve robustness and reduce risk early in the process.
• Develop and review detailed combustor hardware, including dome, swirler, liner, dilution holes, cooling features, igniter location, and sealing interfaces.
• Support CFD, rig testing, and engine testing to validate assumptions, correlate analytical predictions with measured data, and update the design accordingly.
• Iterate the combustor design through concept, preliminary, detailed, and verification phases until performance, durability, and operability targets are met.
• Collaborate closely with performance, aerodynamics, mechanical design, materials, manufacturing, and test teams to ensure the combustor design integrates cleanly into the full engine system.
• Document design rationale, trade-offs, test findings, and verification evidence to support technical reviews and development gates.

BASIC QUALIFICATIONS

• Master’s degree in Aerospace Engineering, Mechanical Engineering, Thermal Engineering, or a closely related discipline.
• 8–10 years of progressively responsible experience in gas turbine combustion, combustor design, or propulsion system development.
• Strong academic and practical background in gas turbine combustor fundamentals, including fuel injection, swirl and recirculation, flame stabilization, liner cooling, dilution, and turbine inlet temperature management.
• Demonstrated experience in the full combustor design process: concept development, preliminary sizing, detailed design, and verification through analysis and test.
• Proven ability to correlate analytical and CFD results with rig or engine test data and drive design iterations.
• Familiarity with manufacturing processes, geometric tolerancing, and design-for-manufacture principles for high-precision hot-section components.
• Experience working with performance, aerodynamics, mechanical design, materials, and test teams in an integrated engine development environment.
• Strong technical communication skills, including the ability to prepare and present technical reports, design reviews, and risk assessments.

PREFERRED QUALIFICATIONS

• Combustor design and optimization using first principles methods, empirical correlations, and CFD-driven trade studies.
• Proficiency with CAD and engineering analysis tools for combustion, fluid dynamics, heat transfer, and structural assessment.
• Skills in interpreting and troubleshooting test data related to ignition, stability, emissions, pressure loss, and thermal loading.
• Ability to manage multiple design variables and trade-offs under technical, schedule, and resource constraints.
• Strong problem-solving and decision-making skills, with the ability to work independently and exercise technical leadership.
• Effective cross-functional collaboration and stakeholder management across engineering, manufacturing, and test functions.
• Comfort with high-performance, safety-critical environments and a disciplined approach to design verification and documentation.
